4. Why Take This Course?
How many of you have checked your , FB, texts…
Today?
In the past hour?
Since I started talking?
Your hand is still down because you’re online at this very moment

5. Networks and Distributed Systems are Ubiquitous
Touch every part of our daily life
Web search
Social networking
Watching movies
Ordering merchandise
Banking
Dating
Driving directions
Requesting a ride or food …

6. Why Take This Course?
Networking is one of the most critical topics in CS
There would be no…
Web
Streaming media
Big Data
Cloud
Apps or mobile computing
… without networks

7. Goals Fundamental understanding about computer networks
All the way from bits on a wire…
… across the Internet…
… to a complex, distributed application
Focus on software and protocols
Not hardware
Minimal theory
Not software engineering
Project-centric, hands on experience
Real projects, protocols, etc.

9. Teaching Style I am a researcher Solution: ask questions!
Things make sense to me that may not make sense to you
I talk fast if nobody stops me
Solution: ask questions!
Seriously, ask questions
Standing up here in silence is very awkward
I will stand here until you answer my questions
Help me learn your names
Say your name before each question

10. Textbook Two textbooks, both optional
Computer Networks: A Systems Approach (Peterson and Davie, 5th Edition)
Distributed Systems: Concepts and Design (Coulouris etal., 5th Edition)

12. Projects This course is project-centric 5 projects
Designed to give you real networking experience
Start early!
Seriously, start early!
5 projects
Due at 11:59:59pm on specified date
Use turn-in scripts to submit your code, documentation, etc.
Working code is paramount

13. Project Logistics Languages
You may choose the language for the projects
Code must compile on the CCIS Linux machines
Project 1 is out today, due Friday September 21st
Project questions?
Post them on Piazza!

14. Project Groups Projects will be completed in groups of two
Unless we have odd numbers…
Partner selection
Pick whoever you want
You may switch partners between projects
Do not complain to me about your lazy partner
Hey, you picked them
Can’t find a partner?
Post a message on Piazza!

15. Late Policy
Each student is given 4 slip days that they can use at any time to extend a project deadline
You don’t need to ask me, just turn-in stuff late
All group members must have unused slip days
i.e. if one member has zero slip days left, the whole group is late
Assignments are due at 11:59:59, no exceptions
1 second late = 1 hour late = 1 day late
20% off per day late

16. Participation This is a high-level college course
I’m not taking attendance
I don’t care if you skip lecture
That said, please come and participate!
Ask questions!
Ideally, I want to know everyone’s name by the end of the semester

17. Exams Midterm and Final All exams are: 3 hours, out-of-class
Midterm is tentatively scheduled for 6-9pm, Wednesday October 10th
The final will be cumulative
All exams are:
Closed book, leave the laptop at home
If I see a smartphone, I will take it and sell it on ebay
You are allowed to bring an 8.5x11, double-sided cheat sheet

18. Grade Changes
Each student is given 2 challenges to use as they see fit
Challenges can be spent asking for regrades
If you think there has been a grading error, come to my office hours
If the grade is incorrect, you keep your challenge
If the grade is correct, you lose your challenge
When your challenges are exhausted, you cannot ask for regrades

19. Grade Changes (Continued)
Challenges may be used for:
Projects, homeworks, and tests
Challenges may not be used for:
Late assignments, use of slip days
If you want to challenge a project grade, all group members must have an available challenge
Your challenge succeeds or fails as a group

20. Cheating Do not do it Cheating is an automatic zero
Seriously, don’t make me say it again
Cheating is an automatic zero
Must be referred to the university for discipline and possible expulsion
Project code must be original
You and your groupmates only
Unless we give you starter code, obviously
If you have questions about an online resource, ask us
Homeworks must be done individually
Copying answers from friends or former students is forbidden

21. Final Grades
At the end of the semester, all of your grades will sum to 100 points
= 100
Final grades are based on a simple scale:
A >92, A , B , B 83-86, B , …
I don’t curve grades
Homeworks
Projects
Exams
